Just one minor quibble: I think you should have put the explanation for why you chose the male/female examples (“The male/female distinction isn’t rigid; it just helped organize the data in a way that made this distinction pop out for me”) much earlier in the post. Since agreeing or disagreeing with your generalization has nothing to do with agreeing or disagreeing with your conclusion, you should say so before the beginning of the second section.
